A CI Butterfly Valve (Cast Iron Butterfly Valve) is a type of quarter-turn valve commonly used for regulating or isolating flow in pipelines. Its compact design, cost-effectiveness, and ease of operation make it ideal for a wide range of industrial, commercial, and waterworks applications.
The main body of a CI Butterfly Valve is made from high-quality cast iron, which provides strength, durability, and resistance to wear and corrosion under normal operating conditions. The valve consists of a disc mounted on a rotating shaft. When the handle or actuator is turned, the disc rotates a quarter turn (90 degrees) to open or close the valve, allowing or restricting the flow of fluid.
CI Butterfly Valves are widely used in water supply and distribution systems, HVAC, fire protection, irrigation, wastewater treatment, and process industries. Their lightweight construction compared to other types of valves, such as gate or globe valves, allows for easier installation and lower maintenance costs.
These valves are available in various designs such as wafer-type, lug-type, and flanged-end connections, depending on the application and pipeline requirements. They often come with rubber-lined discs (EPDM, Nitrile, or Neoprene) to ensure tight sealing and leak-free operation even at low pressure.
Key features of CI Butterfly Valves include:
Quick quarter-turn operation
Compact and space-saving design
Low-pressure drop across the valve
Suitable for both manual and automated operation
Corrosion-resistant lining options
In summary, CI Butterfly Valves are a reliable and economical solution for flow control across a wide range of industries. Their simple mechanism, robust construction, and versatility make them a preferred choice for engineers and plant operators looking for long-lasting performance and easy maintenance.
